If it wasn’t for those wacky upward adjustments ABC primetime series’ fast nationals had been getting this fall, who knows if Nielsen’s processing error would’ve been discovered? After keeping mum on the controversy for weeks, the ratings measuring giant publicly admitted Friday that a glitch had been inflating ABC’s Live+Same Day ratings and that the software problem actually had been skewing the network’s numbers since March. As a result, revised Live+SD ratings were released today for ABC’s Premiere Week performance.

While the blunder is a big blow to the reputation of Nielsen, already seriously challenged by upstart media measurement companies. Thankfully for ABC, the revisions reduced its averages but didn’t change the narrative, with the network’s position in primetime, late-night as well as the morning program and evening newscast races unchanged.

The crazy three-tenth and two-tenth adjustments, including for low-profile new series, are gone. Originally, of the 18 ABC primetime programs that aired during premiere week, all but two had their fast nationals adjusted — all upward — with two adjustments of .3 and four of .2.

IELIZABETH LAIL, GEORGINA HAIGn the revised ratings, only five ABC series received upward adjustments — .1 for all — the usual suspects Modern Family (3.8), Marvel’s Agents of S.H.I.E.L.D. (2.0), Once Upon a Time (3.5), Grey’s Anatomy (3.1) and The Goldbergs (2.4). What’s more, two series, Nashville (1.4) and Revenge (1.3), were adjusted down a tenth, the first time an ABC series has received a downward adjustment this fall.

Ultimately, only four ABC programs, Black-ish (3.3),The Goldbergs (2.4), Grey’s Anatomy (3.1) and 20/20 (1.6) were able to keep their original Premiere Week Live+Same Day 18-49 ratings. All other series were revised down.
